Trait: Boobjob

Mammary intercourse is a sexual act in which a woman stimulates a man's penis by rubbing it between her breasts. Alternatively, or additionally, the man may take a more active role by thrusting his penis between her breasts. Mammary intercourse may be combined with fellatio.

Do not confuse this with an alternate meaning of "boob job", referring to augmentive surgery done on the breasts.
